SPECIFIGATIQN forming part of Letters Patent No. 704,866, dated July 15, 1902-.

Application filed December 26, 1901. Serial No. 87,261l (No model.)

To @ZZ whom it 1i/,my cmu/'67%.'-

Be it knownthat I, KARL DEINLEiN, a subject of the Emperor of Austria-Hungary, re-

siding at Pilsen, in the Province of Bohemia, in' the Empire of Austria-Hungary, .have invented certain new and useful, Improvements in Firing-Gear for Ordnance; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures oi' reference marked thereon, which forma part of this specification.

.This invention relates to means for firing guns, according to which on pulling the trigger the striker-spring is iirst compressed and then released for the purpose of shooting for- Ward the striker, but which automatically l returns to its initial position after the trigger has been pulled, whether the charge has been ilred or not, so that the iring-gear can be again operated without its being necessary to manipulate or-interfere with the breech- A block.

.In firing-gearl according to this invention a cooking-leveradapted tobe operated by the trigger acts upon the striker, whose movement inrthe breech-block is suitably guided,

and o'n the vstriker-spring, which is not in,v stress .when in its position of rest. The cock- Aing-lever is influenced by a spring that bears against the back; cover of the iiring-g'ear-and is adapted to maintain it in position in the breechblock and also to hold the striker Vready for firing..

sitiol'l, whereby the cooking-lever and the 'striker are also returned to their original positions, so that the firing-gear isagain brought into positionV for use.I The two-springs may be either parallel to each other or one may Vbe concentricallyinserted in the other, and the cooking-lever may eitherbo moved ldition.

Figs. 11 to 15 are longitiidinal sections showvtirol y closes the rear portion of the re 'the breech-block which contains the :.iring.-

rectly by the trigger or by meansof a separate lever acting upon the trigger.

To obviate risk of tiring the gun when the breech block is not completely closed, the trigger is provided with a projection which can enter a'groove formed in a bolt adapted to be rotated by avcam-lever only when the breech block -is completely closed and the cam-lever is in the position corresponding` thereto, and thereby enable the firing device to be-moved. l

Figures l to 5 illustrate an example of wedge-shaped breech-block provided with liring-gearaccording to this invention. Fig; 1 is a longitudinal section through the rear end of the gun and the breech-block, showing the parts in the positions they occupy when at rest. Figs. 2, 3, and 4 are longitudinal sections through the breech-block, showing successive positions of the parts when in opera- Fig. 5 is a cross-section through the breech-,block on the line A B of Fig. 1. Fig. 6 is a side elevation of the safetymeans, and Fig. 7 is a horizontal section of a screw breechblock and rear end of a gun provided with viii'ing-gear according to this invention. Figs.

8 tol show another example of suchringgear also arranged lto'suit a Wedge-shapedv breech-block. Fig. 8 is a longitudinal section of the rear end'of the gun and the breechblock, showing the parts in the position they occupy when at rest. Fig. 9 is a rear elevation, partly in section; and Fig. 10 shows in elevation lthe firing and safety devices, while ing the parts'in successive positions theyoccupy during operation. Fig. 16 is a longitudina`l section of a wedge-shaped breech-block and iiring-gear in which the trigger-lever also forms the" iiringflever.

ln the example shown in Figs. l to 5 the striker a is adapted to slide longitudinally in a suitable recess formed in the breech-block, but is not rotatable. There projects into they box of the striker a cyliudricalhollow extension of the supporting-plate e, which isvin, sorted into the breech-block and held therein by means of a bayonet-joint. This plofI engear. In the space formed in the interior of the striker and the extension of the supporting-plate there is placed a striker-spring d, the length of which is such that the point of the striker c is located slightly behind the front surface ofthe breech-block When at rest, and the ends of the strikerspring bear Without pressure, respectively, on the striker and the supporting-plate, Fig. 1.

For the purpose of cooking the striker a cooking device 7L is provided, which is connected to the square pin 7c of the trigger j, which is mounted on the breech-block. This cooking device is formed as a belLcrank lever and is subjected to the pressure of a spring f, which is provided with a sleeve g and of which the other end bears on the plate e. This spring is slightly compressed in the position shown in Fig. 1, so that it secures on the one hand the bayonet-joint of 'the supporting-plate e and on the other hand presses against thesleeve g, thereby maintaining the cooking device 'and the trigger in the positions shown in Fig. 1. A projection 'i at the side of the cooking device presses against the inclined withdrawing projection c on the striker, and therefore holds the striker in its rearward position. The loaded gun can therefbrebeubjected to shocks-for example, while traveling-without any risk, as the striking-spring when in this position 'exerts no pressure on the striker, and the striker in moving forward would have to overcome the increasing pressure of the spring f, that acts on the cooking device.

For the purpose o'f firing the trigger 'y' is moved backward, thus turning the cooking device ll, This at first compre only the spring f-t'. e., until the cooking l rojec'tion i bears on the forward-inclined surface of a part b, that projects laterally from the striker. I

to spring forward into the position indicated in 'nig'. il, in which position the striker comes into contact with the cartridge. if the trigger be now released, the spring f, acting upon the cocking device, nieves it back, and the trigger-connected therewith is moved forward until the projection on the cooking de- .vice bears against the withdrawing. projection c, as shown in Fig. Further pressure ol the spring f causes the projection 'L' to bear onpthe inclined surface otl the projection c, and thereby draw the striker into the position of'rest, Fig. 1, in which position either the breech can be opened or a fresh shot can be red, in which latter case the before-inentioned operations are repeated.

In order to render-discharging possible only when the breech is completely closed and to prevent the operation of the tiring-gear in any other Iposition of the breech-block, there is provided a safety device, as shown in Figs. 5 and 6, 'which comprises a projection 1 on the triggerj and a groove 2, cnt in the pivot 'n of the cam-lever m, these parts being adapted` to engage with each other only when the breech-block is completely closed, and therefore only When the cam-lever is in the position corresponding thereto, so that the trigger j can then be moved.

The repeating firing-gear hereinbefore described can be used also in a similar manner with screw breech-blocks, as shown in Fig. 7. The construction and operation of this arrangement will be obvious from what has been stated above.

In the example shown in Figs. 8 to 16 the striker a, which ismovable in an axial direction, but is prevented from rotating, contains the uncompressed striking-spring d, in conjunction with the sleeve-like extension of the supportingplate c and is provided with a sleeve y, `which is guided in the breech-block Iand on which the spring f, that effects the return movement'of the ltriggerj, acts. ,The' spring fis arranged concentrically with the strikingspring and surrounds' the striker a. The cooking device h, Wh ich is connected with the trigger-lever by means of the squared pin 1, is in the form ofa cani and is provided with a notch in addition to the projection. t, tho projection c of the sleeve y extending into the said notch. When the tiring-gear is in its normal position, Fig. 8, the spring f by means of bars g', projecting from the sleeve, prevents the supportingplate e from being rotated and falling out and also holds the striker in its normal position. The triggerj is operated in this case by drawing the ringlever Z, which is pivoted independently of the IIO breech-block on the rear end of the gun, and

the cain li is thus rotated in such a way that its projection t', in conjunction with the projection b, acts on the striker in the manner hereinbefore described. The striker is consequently pushed backward and at the same time the sleeve g is pulled forward by the projection c on the cam, so that the spring j is still further compressed, Fig. 1l.

Vtfhen the strikerand the sleeve are in their extreme end positions, Fig. 12, the projection L releases the projection Z1 and the striker can spring forward and enter the cartridge in consequence of the forward position of the sleeve y, Fig. 13.

When the firing-lever] is released, so that the trigger j is also released, the spring j' presses the sleeve g backward, Fig. 14, and by means of the projection c this sleeve rotates the cooking device 71, and also moves the leversy and l into their initial positions, the striker being' drawn back behind the Eront 4surface of the breech-block in consequence of the pressure'of the sleeve upon it, Fig. 15,

.v means of two links, as soon as the breech-l Vengagement; withnotches on the supportingplatee (shown in Fig. 15) for the purpose of securing the latter.-

When the breech-block is insuflicientiy closed, firing is prevented by means of the projection 1, Figs. 9 and 10, which is mounted on the trigger j and can enter avgroove 2 on a pivot n, connected to the cam-lever by block is completely closed and the cam-lever assumes the positioncorresponding thereto.

The trigger 7' can also be formed as a firinglever, as shown in Fig. 16.

The form of construction of the tiring-gear according to Figs. 8 to 15 can be used, in a similar manner to that according to Figs. 1 to 5, also for screw breech-blocks.
